Observe the diagram given alongside carefully and answer the questions below. After ten minutes of keeping the set-up as shown in the figure, the colour of the iron nail changes, what does this indicate?

When a piece of iron metal is placed in copper sulphate solution, then iron sulphate solution and copper metal are formed. CuSO 4 ( aq ) + Fe ( s ) → FeSO 4 ( aq ) + Cu ( s ) . In this reaction, iron displaces copper from copper sulphate solution. The deep blue colour of copper sulphate solution fades due to the formation of a light green solution of iron sulphate. A red-brown coating of copper metal is formed on the surface of the iron metal. This reaction occurs because iron is more reactive than copper. It is a type of displacement reaction.

Observe the diagram given alongside carefully and answer the questions below. Name the type of chemical reaction that take place between copper sulphate and iron nail.

When iron is added to a copper sulphate solution, it displaces the copper metal from the copper sulphate solution to form iron sulphate. It is a type of displacement reaction. CuSO 4 ( aq ) + Fe ( s ) → FeSO 4 ( aq ) + Cu ( s ) . The copper sulphate solution colour changes from blue to pale green.

Observe the diagram given alongside carefully and answer the questions below. Which of the two metals involved in the given process is more reactive.

Iron and copper are the two metals involved in the given process. This reaction has occurred because iron is more reactive than copper. When iron is added to a copper sulphate solution, it displaces the copper metal from the copper sulphate solution to form iron sulphate. It is a type of displacement reaction. CuSO 4 ( aq ) + Fe ( s ) → FeSO 4 ( aq ) + Cu ( s ) . The copper sulphate solution colour changes from blue to pale green.

Observe the diagram given alongside carefully and answer the questions below. What changes do you expect in the reaction mixture, if a copper wire is kept immersed in an iron sulphate solution?

When the copper wire is immersed in an iron sulphate solution then there is no reaction take place between the metals because copper is less reactive than iron, so it can't displace iron from iron sulphate solution. Cu s + FeSO 4 aq → X ( no reaction ) .
